yes I agree with Wade I dont seperate my males either I did once as my male was poorly but now they all stay together and one of my litters that only had one male and a female in I kept 2 of her girls back and now all 3 girls are expecting, I also set up some new cages with some of my offspring and have about 4 others all due, once you have a nice pair together its not worth the hassle of taking males out as it can be a nightmare to reintroduce them.
